As of December 31, 2017, 2016 and 2015, the balance of goodwill reported in the table above included accumulated impairment charges of $4.3 million and $11.7 million in our APC and PEP segments, respectively, all of which were recorded during the year ended December 31, 2008.

The goodwill acquired in 2017 is related to the Vandalia acquisition as described in Note 3 and is derived from the value of the businesses acquired. This fair value was based on management business plans and future performance estimates which are subject to a high degree of management judgment and complexity. Actual results may differ from these projections and the differences may be material, leading to a potential impairment of this goodwill if this reporting unit’s future results are not as forecasted.
